BEZEICHNUNG
LampenabdeckungDESIGNATION
Lamp cover
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft eine Lampenabdeckung in Form eines einstückigen Hohlkörpers aus einem transparenten thermoplastischen Kunststoff, der eine Öffnung zur Einführung der Lampe und zur Befestigung an einem Leuchtenträger aufweist, wobei auf der Außenfläche des Wandkörpers eine Deckschicht aus einem UV-absorbierenden Acrylat vorgesehen ist.The invention relates to a lamp cover in the form of a one-piece hollow body made of a transparent thermoplastic material, which has an opening for inserting the lamp and for fastening to a lamp support, wherein a covering layer made of a UV-absorbing acrylate is provided on the outer surface of the wall body.
Lampenabdeckungen dieser Art sind bereits in verschiedenen Formen im offenkundigen Gebrauch und somit allgemein bekannt. Weil die dazu verwendeten Kunststoffe unter der Einwirkung von UV-Strahlen im Laufe der Zeit mehr und mehr verspröden und somit zerbrechlich werden, und außerdem vergilben, haben derartige, insbesondere im Freien verwendeten Lampenabdeckungen eine vor UV-Strahlen schützende Außenschicht.Lamp covers of this type are already in public use in various forms and are therefore generally known. Because the plastics used for this purpose become more and more brittle and therefore fragile over time under the influence of UV rays, and also turn yellow, such lamp covers, especially those used outdoors, have an outer layer that protects against UV rays.
Die neuerdings mit zunehmender Verbreitung in den Verkehr kommenden Halogenlampen, namentlich Quecksilberdampflampen erzeugen ebenfalls UV-Strahlen. Sie bewirken damit in erheblichem Ausmaß eine Ozonisierung der die Lampe umgebenden Luft. Insbesondere bei Außenleuchten bildet die Lampenabdeckung eine geschlossene Kammer, in der praktisch kein Luftaustausch mit der Außenluft erfolgt. So baut sich innerhalb der Lampenabdeckung eine sehr hohe Ozonkonzentration auf. Es ist allgemein bekannt, daß durch Ozon Alterungsprozesse beschleunigt werden. Davon ist auch das Material des Wandkörpers der Lampenabdeckung betroffen, die beim Einsatz neuer Leuchtmittel aggressiven Einflüssen nicht nur von außen, sondern auch von innen ausgesetzt ist. Und das nicht nur durch UV-Strahlen, sondern auch durch eine hohe Ozonkonzentration der Luft innerhalb der Lampenabdeckung.Halogen lamps, namely mercury vapor lamps, which have recently become increasingly common, also produce UV rays. They therefore cause a significant amount of ozonation of the air surrounding the lamp. In the case of outdoor lights in particular, the lamp cover forms a closed chamber in which there is practically no exchange of air with the outside air. A very high concentration of ozone builds up inside the lamp cover. It is generally known that ozone accelerates aging processes. This also affects the material of the wall body of the lamp cover, which is exposed to aggressive influences not only from the outside but also from the inside when new lamps are used. And not just from UV rays, but also from a high concentration of ozone in the air inside the lamp cover.
Die bisher bekannten Lampenabdeckungen der eingangs definierten Gattung sind gegenüber solchen zerstörenden Einflüssen aus dem Innenraum nicht geschützt. Der Erfindung liegt daher die Aufgabe zugrunde, diesem Mangel abzuhelfen bei Verwendung der gleichen den Wandkörper der Lampenabdeckung bildenden Kunststoffe.The previously known lamp covers of the type defined at the beginning are not protected against such destructive influences from the interior. The invention is therefore based on the task of remedying this deficiency by using the same plastics that form the wall body of the lamp cover.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Lampenabdeckung der in der Beschreibungseinleitung und im Oberbegriff des Anspruchs 1 definierten Gattung auf der Innenseite des Wandkörpers eine Innenschutzschicht aus einem sowohl UV-Strahlen absorbierenden, als auch Ozon-undurchlässigen Acrylat angeordnet ist. Weitere Merkmale der Erfindung gehen aus den Ansprüchen 2 und 3 hervor.The stated object is achieved according to the invention in that a lamp cover of the type defined in the introduction to the description and in the preamble of claim 1 has an inner protective layer on the inside of the wall body made of an acrylate that absorbs UV rays and is impermeable to ozone. Further features of the invention emerge from claims 2 and 3.
Die Erfindung wird im Folgenden näher erläutert. Anhand einer Zeichnung wird ein Ausführungsbeispiel beschrieben.The invention is explained in more detail below. An embodiment is described using a drawing.
Die Zeichnung zeigt mit teilweisem Schnittbild durch die Wand eine kugelförmige Lampenabdeckung. Ihr Wandkörper 1 ist als ein beispielsweise in einem an sich bekannten Rotationsschmelzverfahren aus einem thermoplastischen Kunststoff, z.B. einem Polycarbonat, hergestelltes Formteil ausgebildet. Auf ihrer Außenfläche ist in an sich bekannter Weise eine Schutzschicht 2 aus einem UV-Strahlen absorbierenden Acrylat vorgesehen. Als Schutzelement gegen von der Lampe ausgehende, außer von den UV-Strahlen insbesondere auch von der extram hohen Ozonkonzentration beruhenden zerstörenden Einflüssen ist zusätzlich eine innere Schutzschicht 3 angeordnet. Diese besteht ebenfalls aus einem Acrylat, welches bei seiner UV-Strahlen absorbierenden Wirkung auch Ozon-undurchlässig ist. Die Lampenabdeckung weist nur eine Öffnung 4 zur Einführung der Lampe und zur Befestigung an einem Leuchtenträger auf.The drawing shows a spherical lamp cover with a partial cross-section through the wall. Its wall body 1 is designed as a molded part made from a thermoplastic, e.g. a polycarbonate, for example in a known rotational molding process. On its outer surface, a protective layer 2 made of an acrylate that absorbs UV rays is provided in a known manner. An inner protective layer 3 is also arranged as a protective element against destructive influences emanating from the lamp, not only from the UV rays but also from the extremely high ozone concentration. This also consists of an acrylate, which, in addition to its UV-ray-absorbing effect, is also impermeable to ozone. The lamp cover has only one opening 4 for inserting the lamp and for fastening it to a lamp support.
Die Vergegenständlichung des Erfindungsgedankens ist nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Der Wandkörper kann auch aus einem anderen Material, z.B. einem Polyamid oder Polyethylen bestehen. Er kann eine andere Form haben und auch nach einem anderen Verfahren, z.B. einem an sich bekannten Spritz-Blasverfahren als einstückiges Formteil hergestellt sein.The embodiment of the inventive concept is not limited to the embodiment described above. The wall body can also be made of a different material, e.g. a polyamide or polyethylene. It can have a different shape and can also be manufactured as a one-piece molded part using a different process, e.g. a known injection-blow molding process.
